Quickstart

This repository provides a petroleum-engineer-friendly coverage map of the public Equinor Volve dataset.

It does not crawl the dataset. It uses a frozen metadata catalog and produces structured data-availability tables.

What problem does this solve?

The Volve dataset is a field archive release, not a curated research dataset.

Before starting any study, you should know:

  • Which wells actually have drilling telemetry?
  • Which wells have structured daily drilling reports?
  • Which wells have wireline logs?
  • Which wells have reservoir models or seismic data?

This repo answers those questions.

Step 1 — Start with the well matrix

Open:

  • outputs/coverage_matrix_binary.csv

Rows are wells. Columns are petroleum data categories. Value is 1 (present) or 0 (not present).

Use this to:

  • Select wells for drilling studies (look for DDR_XML, WITSML or XML, and WELL_TECH or DOCS).
  • Select wells for log-based studies (look for DLIS and/or LAS).
  • Avoid data-poor wells.

Step 2 — Rank wells by data richness

Open:

  • outputs/coverage_by_well.csv

Columns:

  • well
  • total_files
  • data_categories_present

Use this to identify high-coverage wells and avoid wells with narrow scope.

Step 3 — Understand dataset composition

Open:

  • outputs/coverage_by_tag.csv

This tells you how the dataset is distributed across disciplines.

Examples:

  • High WITSML count suggests drilling telemetry is abundant.
  • DLIS and LAS indicate wireline logs exist.
  • SEGY indicates seismic is present.

Important notes

  • System-level archive folders were excluded to prevent distortion of coverage statistics.
  • Well identifiers were extracted from file paths.
  • Field-level data (models, seismic packages, general documents) may not appear in well-level tables.

Recommended use in papers

You may cite this coverage audit methodology as:

“Prior to analysis, a filesystem coverage audit of the Volve dataset was performed to identify wells with sufficient operational and logging data.”
